Multivariate metal-organic frameworks for fine-tuning light emission

Abstract

Multivariate metal-organic framework compositions and methods of producing multivariate metal-organic frameworks. The metal-organic framework including at least one light-emitting linker in an amount sufficient for the composition to produce broadband emission spectra in high efficiencies.

What is claimed is: 
     
       1. A method of producing a light-emitting metal-organic framework, the method comprising:
 combining at least one light-emitting linker precursor, having a formula selected from the group consisting of: 
 
       
         
           
           
               
               
           
         
         
           
           
               
               
           
         
         with a non-fluorescent linker, having a formula: 
       
       
         
           
           
               
               
           
         
       
       to form a first mixture; 
       adding an acid to the first mixture to form a second mixture; and 
       heating the second mixture. 
     
     
       2. The method of  claim 1 , wherein heating the second mixture comprises raising a temperature of the second mixture above 100 degrees Celsius. 
     
     
       3. The method of  claim 2 , wherein heating the second mixture is conducted for a period of at least 4 hours. 
     
     
       4. The method of  claim 2 , wherein adding the acid is conducted under a stream of argon. 
     
     
       5. The method of  claim 2 , wherein the acid is acetic acid.
